52 THE FOSSIL CORALS AND 



Genus CYCLOLITES. 



Cyclolites, Lamarck, Syst. des Anim. s. Vert. p. 369. 



1. Cyclolites alpina, B'OrUgny sp. Plate XIII, Figs. 8, 9. 



This European Eocene coral is noticed by D'Orbigny as Fwnginella alpina, Prodr. 

 de Paleont. t. ii. p. 403 (1850). Subsequently Milne Edwards and Jules Haime 

 noticed it as a doubtful Cyclolites in 1851 ; and, finally, Jules Haime determined this 

 to be its proper generic position in 1854. 



The specimen from Sind is from the Eanikot group, three miles west of Lynyan. 

 Survey-number G xl§«- 



It is a broad and very shallow form, with thin margins. The lower surface is 

 slightly projecting at the position of the peduncle, and shows feeble circular ridges 

 of epitheca. The epitheca is delicate and permits the costse to be seen. The upper 

 surface is very flat. The septa are very numerous, crowded, and unequal ; there 

 are more than six cycles of them. The coral is circular in outline. The breadth of the 

 calice is 1 j^ inch and the height about ^ inch.

2. Cyclolites Eanikoti, Duncan. Plate XVII, Figs. 5, 6. 



The corallum is circular in outline and concave below, where there is a feeble 

 epitheca barely marked with concentric rings. Above, the coral is slightly convex, 

 with rather a blunt marginal edge. The fossa is very small and circular. The septa are 

 thin, not very close (for the genus), furnished with numerous and visible synapticulse, 

 unequal, usually straight and plain, having a sharp keen edge. The smaller septa cling 

 to the margin, and the larger are broadest near the fossa ; and there are in all from 

 280 to 300 septa.

Cyclolites Eanikoti, Duncan. Variety. 



A variety of the species occurs at Jhirk, in the Eanikot group. Survey-number 

 Gr ft 4a- It has smaller septa, which are rounded where free, instead of being sharp- 

 edged ; moreover, the septa are dentate in the fossa.

The corallum is circular in outline, flat beneath, and is marked with a strong
